Question

Find the value of g(x)=2-x^2 and f(x)=2x-1 , a, g(-8)

Answer 1

Solve for the function of g then use what you get for g to solve for f.

g(-8) = 2 - (-8)^2

g(-8) = 2 - 64

g(-8) = -2

f(-2) = 2(-2) - 1

f(-2) = -4 - 1

f(-2) = -5

Best of Luck!

Answer 2

-62

Explanation:

g(x)=2-x^2

Let x = -8

g(-8)=2-(-8)^2

= 2- 64

= -62
